Russound PRO-12 HP Impedance Matching Speaker Selector for 12-Pairs

Centralize and safeguard multiroom audio distribution for commercial, retail, or security applications with the Russound PRO-12 HP speaker selector. Engineered for demanding environments, this 12-pair speaker selector lets you drive up to 12 zones from two source amplifiers while preserving amplifier health and consistent audio levels. Audiophile-grade autoformers provide impedance matching for 4Ω or 8Ω speakers and a rear rotary switch configures the amplifier load based on connected zones. The PRO-12 HP's low-frequency protection circuit reduces subsonic signals to prevent amplifier shutdown, enabling higher power operation for paging, monitoring and background music in surveillance and security systems. Installers benefit from color-coded detachable snap connectors and printed room labels that speed termination and troubleshooting. At 17
